Federal Communication Commission Interference Statement

This device complies with Part 15 of the FCC Rules. Operation is subject to

the following two conditions: (1) This device may not cause harmful

interference, and (2) this device must accept any interference received,

including interference that may cause undesired operation.

This equipment has been tested and found to comply with the limits for a

Class B digital device, pursuant to Part 15 of the FCC Rules. These limits

are designed to provide reasonable protection against harmful interference in a

residential installation. This equipment generates, uses and can radiate radio

frequency energy and, if not installed and used in accordance with the

instructions, may cause harmful interference to radio communications.

However, there is no guarantee that interference will not occur in a particular

installation. If this equipment does cause harmful interference to radio or

television reception, which can be determined by turning the equipment off

and on, the user is encouraged to try to correct the interference by one of the

following measures:

- Reorient or relocate the receiving antenna.

- Increase the separation between the equipment and receiver.

- Connect the equipment into an outlet on a circuit different from that

to which the receiver is connected.

- Consult the dealer or an experienced radio/TV technician for help.

FCC Caution: Any changes or modifications not expressly approved by the

party responsible for compliance could void the user's authority to operate this

equipment.

This transmitter must not be co-located or operating in conjunction with any

other antenna or transmitter.

For operation within 5.15 ~ 5.25GHz / 5.47 ~5.725GHz frequency range, it is

restricted to indoor environment. The band from 5600-5650MHz will be

disabled by the software during the manufacturing and cannot be changed by

the end user. This device meets all the other requirements specified in Part 15E,

Section 15.407 of the FCC Rules.

Radiation Exposure Statement:

This equipment complies with FCC radiation exposure limits set forth for an

uncontrolled environment. This equipment should be installed and operated

with minimum distance 20cm between the radiator & your body.

Note: The country code selection is for non-US model only and is not

available to all US model. Per FCC regulation, all WiFi product marketed in

US must fixed to US operation channels only.
